I borrowed a friends Gutar hero III so my son could try it and see if he likes it, he played for a few hours, then he ejected the disk put it in its case and we then watched some television, after a bit he put the game back in and it would not work kept saying cannot read disk please refer to your wii manual, I figured he had messed up the game so I then purchased him another to replace hers, he played it for a while, the next day when he put it in guess what it too would no longer work, ALL of his other wii games are working fine including gamecube games so now I have two guitar hero games disks that are not working?
